D'Leh is a hunter in the movie 10,000 B.C. He falls in love with Evolet, only to watch her get captured by a band of mysterious warlords. D'Leh leads a small army in search of Evolet, only to encounter numerous other civilizations along the way, all of whom have suffered at the hands of the aforementioned warlords.
In the end, D'Leh comes to understand that he has been called to save not only Evolet... but all of civilization. No pressure, though.
